#1 Lewis Hamilton and Nicole Scherzinger

The Pussycat Dolls' lead singer is widely rated by fashion magazines as one of the most high profile performers in the world. She has backed this up with her talent and has a very successful career in music, television, and theatre.
Nicole, often called 'Hawaiian Pop Goddess' gets along famously with Lewis Hamilton's family and he credits her for being his source of inspiration. The couple was lapped up by the British media and they were a consistent feature of tabloids - as a world champion and an internationally popular pop-star duo ought to be.
The couple dated on and off from 2008-15 after meeting at the 2007 MTV Europe Music awards. They went their own way after Hamilton won his second title.
